Well, that depends on her interests and personality! If she's a girly girl, consider fashion or beauty products. If she's more active and outdoorsy, perhaps a new sporting equipment or bike would be more up her alley. If she's into arts and crafts, she might enjoy a fun new hobby kit or a new set of art supplies. You could also consider giving her a gift card to a store that she loves or even just a special day out with you doing something she enjoys!
